There is need for a course that is targeted toward emergency physicians and trainees without formal disaster training. This course should be available online and should utilize a mix of educational modalities, including lectures, scenarios, and virtual simulations. An ideal course should focus on disaster preparedness, and the clinical and non-clinical aspects of response, with a focus on an all-hazards approach, including both terrorism-related and environmental disasters.

Hemorrhage control supplies are being issued to less than half of the responding officers. When used, these interventions were generally thought to be effective. Further study is needed to delineate specific medical interventions, and therefore training and equipment, needed by law enforcement personnel.
The time to successful ETI was not significantly different between VL and DL. Video laryngoscopy had a greater perceived ease of use, but DL was perceived to be more feasible for use in actual HazMat situations. These findings suggest that both DL and VL are reasonable modalities for use in HazMat situations, and the choice of modality could be based on the clinical situation and provider experience.
A 67-year-old man with type 2 diabetes mellitus presented after an out-of-hospital cardiac arrest with pulseless electric activity (PEA) preceded by significant chest discomfort and syncope. Cardiopulmonary resuscitation was started for PEA arrest with return of spontaneous circulation after 20 minutes. His initial ECG showed an acute inferior ST-segmentelevation myocardial infarction (STEMI; Figure 1). In the emergency department, he experienced another PEA arrest and an ECG showed evidence of a moderate pericardial effusion. Attempts on pericardiocentesis were unsuccessful, and he was brought to the catheterization laboratory in cardiogenic shock on vasopressors.Emergent coronary angiogram demonstrated a completely occluded proximal right coronary artery with an intracoronary thrombus with moderate disease in the left anterior descending artery and left circumflex arteries (Figure 2A The patient required ≈60 minutes of external chest compression support to maintain peripheral perfusion. The patient was rapidly transported to the operating room for emergent cardiac surgery. The pericardium was opened, and hemodynamics rapidly improved. The patient was quickly supported on cardiopulmonary bypass. On direct inspection, an extensive right ventricular infarct was identified, extending along the basal inferior wall of the left ventricle adjacent to the septum. The myocardium was extremely fragile, and free-wall rupture was identified. Patch repair of the rupture was expeditiously performed without complication. Because of the extensive right ventricular infarct and duration of external cardiac compressions, extracorporeal membrane oxygenation support was required. Prolonged CPR had also caused extensive rib fracturing, leading to diffuse bleeding, which was managed with direct ligation/cautery of bleeding sites and multiple rounds of intravascular blood product therapy. The patient never demonstrated signs of neurologic recovery after prolonged CPR and was found to have a large intracranial bleed with uncal herniation. Support was withdrawn 8 days after presentation.Free-wall cardiac rupture is more common in the anterior and lateral walls of the left ventricle and is associated with old age, lack of collateral circulation, or ischemic preconditioning and presentation with first myocardial infarction, as in our patient. The overall incidence of cardiac rupture after STEMI ranges from 0.8% to 6.2%.1 The most common presentation is with PEA and pericardial effusion; however, nearly half of the deaths from cardiac rupture occur as out-of-hospital sudden deaths and never present to the hospital.2 Cardiac rupture typically occurs within 1 to 4 days after the infarct; however, widespread use of fibrinolytic therapy and percutaneous coronary intervention has led to a decline in incidence and a trend toward earlier rupture. A recent series demonstrated a reduction in the overall incidence of free-wall rupture in the modern era, at 1.3%; however, 47.1% of these patients experienced free-wall rupture within the first 24 hour...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
